Answer:
Now 7 remains without a pair and therefore 7 should be multiplied to 112 to make it a perfect square. Similarly 28 should be multiplied to 784 to make it a perfect cube.
Answer:
r =
Step-by-step explanation:
In order to make 'q' the independent variable in the equation, you need to solve for 'r'. The dependent variable would be 'r' because it depends on the value of 'q' to be solved. We can solve for 'r' by using inverse operations and completing the same operation on both sides of the equation. Starting with the initial equation and solving for 'r':
-7q + 12r = 3q -4
Add '7q' to both sides: -7q + 7q + 12r = 3q - 4 + 7q or 12r = 10q - 4
Divide all terms by 12: 12r/12 = 10q/12 - 4/12
Simplify: r =
De acordo com a disponibilidade da unidade, há apenas a seguinte dosagem: 1g/2mL - ou seja, uma grama de dipirona a cada 2mL
O enunciado está meio mal formulado, pois é dito que foram prescritos 500mg de dipirona e é essa quantidade de farmaco que a criança tem que tomar. Deseja-se saber quantos mL deverao ser administrados.
Fazendo a classica regra de 3, podemos chegar no volume desejado:
(atentar que 500mg = 0,5g)
g mL
1 --------- 2
0,5 --------- X
1 . X = 0,5 . 2
<h3>X = 1mL</h3>
Answer:
a = 30°
Step-by-step explanation:
We need to find the value of a.
We know that, a straight line makes an angle of 180°.
In this case,
a+3a+2a = 180
6a = 180
a = 30°
So, the value of a is equal to 30°.
Answer:
Step-by-step explanation:
we know that
The lateral area of a cone is equal to
where
r is the radius of the base
l is the slant height
we have
----> the radius is half the diameter
To find the slant height apply the Pythagoras theorem
substitute the values
